' vns claims. (01.132-345/ The present invention relates lto haircurlers and more particularly to an improved hair (curler which issimple and economical tomanufacture and which is easily operated by theuser.

The present invention relates tor hair curlers be wound.

Preferably the curl `bar is hollow anda-*may be perforated, and asuitable gripper may be employed whereby one 'end ofthe curl may besecured to the lbar. In order to preventcthe curl from unwinding fromthe bar it is necessary to provide some means which will restrain'theuncurling motion,v and in the past this has been accomplished by a wiremember secured to the bar and gripping member; kSucharrangement does notpermit the curl `to be'woundtightly against the head of the person sincein winding it is not possiblev to judge with great accuracy how manyturns of the bar are required to form a curl and hence'a fixedrestrainingmember may be a fraction of a turn removed from the mostdesirable restraining position. Other devices have provided a hair pinlike member'inserted in a hollow bar-but such device has certaindisadvantages, particularly when used with a perforated hollow :barinthat it is difiicult to insert the device into the bar'and the roughinterior of the bar does not readily permit the placementofthe wiremember in the most desired restraining position. f

providinga curling barv having lat the end thereof an extension portionadapted to receive arrestraining member which is resiliently retained inthe desired position so as to have adequate inherent rotation resistingaction relative-to the bar. Y

It therefore is an object of the present invention to provide animproved curling bar with a restraining or lock member'whichobviatescertain disadvantages/of the devices of 'the prior.V art.

Other and further objects of the invention subsequently will becomeapparent from the following description taken in conjunction with theaccompanying drawing in which Figure 1 is a perspective view of a haircurler y in operating position with a curl formed thereabout;

` Figure 2 is an end view of the curl shown in Figure 1; Y Y y Figure 3is one embodiment of the present invention;

Figures 4 and 5 are detailedl views of a portion of the type comprisingarbar on which a curl may In accordance with the present invention the vabjove mentioned disadvantagesfare overcorneby` ofthe device showninFigureB explanatory of the construction and voperation thereof;

Figure 6r shows the construction used where the curling bar, has a`greater diameter thanv that shown in Figure 3; and

Figure '7 shows another form of the locking or restraining member. 'l

Referring to the drawing a curler i0 is shown in Figure 1 having'thereonacurl I2 held in position by arestraining or locking member I4. In

,winding the curl the curlerris rotated in the direction of the arrowsshown in Figure 1 and when the curl has'been completed the lockingmember I4 is rotated in an opposite direction to that shownA bythe.arrows inthe figure.

,The details ofthe curler I0 and the locking member I4 are illustratedvin Figures 3, 4, ,and 5 from which it becomes apparentthatthe curler I0is provided with a hollow perforated bar portion I6 which ispivotallyconnected at I8 to a gripping member 20. The gripping member 20is 'biased 'towardthe `bar l'by a suitable spring 22 mounted adjacentAthe 'handle portions of the curler. At theopen end ofthe curler I0there is mounted in the hollow bar I6 ian extension member 24 which'formost sizesof curlers preferably is of Vhollow construction.` ,The'locking member I4 is mounted on the outer extremity of the extensionmember `2|Iby a member 26 comprising a resilient helical spring havinga' stop portion 2K8 Y adapted to engage the endl fof the extension 24.Inforder to-provide'the desired vdegree, of resistance against rotation:between the lockingv member I4 and the curler I at least one of thecon- YVolumens 3o of thehelicai. spring ze isfbffset slightly so thatits .center does not coincide with the aXis of Athe remainder of theconvolutions.

, Figure 4 illustrates how the outer extremity of the reduced'diameterextension portion 24 is inserted into the helical spring portion 26wherey it isabout to engage theslightly displaced convolution 3D. InFigure 5 it will be seen that thecon- `volution 30 is in'substantialalignment with the Van extension member 24a is inserted within thecurler Illa so that the reduced end portion 2'5 thereof extends beyondthe end of the curling bar |6a. The diameter of the extension portion 25is the same diameter as the extension portion 24 of Figure 3 so that thesame size locking member I4 may be used interchangeably with differentsize curlers.

In Figure 7 there is shown a curler l0 having an extension .24 embodyingthe same general structure as that shown in Figure 3. The locking member30 has a helical spring gripping portion 32 one convolution of which maybedisplaced in the manner of the convolution 30 of the previousembodiment, and the locking member terminates in a handle portion 34.The handle portion 34 will facilitate the rotation of the locking member30 when the curling operation takes place as was explained in connectionwith Figure 1.

While for the purpose of illustration and description, certain specificembodiments of the present invention have been shown, it is to beunderstood that the invention is not to be limited thereby sinceobviously such variations may be made as are commensurate with the scopeof the appended claims.

The present invention is hereby claimed as follows:

l.k A hair curler comprising a hollow bar on which a strand of hair maybe wound, said bar being provided with an extension and a removablerotatable locking member adapted to maintain the strand in woundcondition, said locking member comprising an exterior arm portion spacedfrom the surface of said bar to overlie the curl and a portionresiliently mounted 'on the exterior o'f an extension of said bar so asto have inherent rotation resisting relation therewith.

2. A hair curler comprising a hollow bar on which a strand of hair isto' be wound, an extension for said bar carried thereby ademountablelooking member adapted to maintain the strand in 'Wound conditioncomprising an arm portion spaced from the surface of said bar to overliethe curl and a resilient coil spring portion adjustably mounted on theexterior of an extension 'of said bar 'so as to have inherentrotationresisting relation therewith.

3. A hair curler comprising a hollow bar on which a strand of hair maybe wound, an extension member having a portion thereof rigidly 'mountedwithin said hollow, bar and extending rigidly mounted within said hollowbar and having a portion extending beyond the end ofvsaid bar, and alock member rotatably carried by said extension member and having an armspaced from the surface of said bar to overlie the curl and a resilientportion in engagement with said extension member to resist rotation ofsaid arm relative to said bar, said lock member being adapted to bemoved to an adjusted position to maintain the strand lin woundcondition.

5. A hair curler comprising a hollow bar on which a strand of hair maybe wound, gripping` which a strand of hair may be wound, an extensionmember positioned at the end of said bar, said extension member being oflesser diameter than said bar, and a lock member to maintain the strandin wound condition, said lock member being carried on said extensionmember by a helically wound generally cylindrical shaped spring portionhaving at least a portion of one convolution thereof off-center so thatthe center 'thereof is no-t coincident with the center of the remainderof the member, said lock member being mounted by said spring forrotation to an adjusted position to maintain the strand in woundcondition.

'7. A hair curler comprising a hollow bar on which a strand of hair maybe wound, said bar having an extension portion beyond the portion onwhich the strand is wound, and an adjustable locking member 'adapted tobe moved to adjusted position Vrelative to said bar to maintain thestrand in wound condition, said locking member comprising an exteriorarm portion spaced from the surface of said bar to overlie the curl anda resilient portion mounted on 'the exterior extension of ysaid bar soas to have inherent rotation resisting relation therewith normally toretain said locking member in adjusted position.

8. A hair curler comprising a hollow bar on which a strand of hair is tobe wound, said bar having an extension portion beyond the portion onwhich the strand is wound a demountable wire locking member adapted tomaintain the strand in wound condition comprising a wire arm portionspaced from the surface of said bar to overlieV the curl and a resilientcoil spring portion mounted'on the exterior of an extension of said barVso as to have inherentl rotation resisting relation therewith.
